Now consider the collision represented in the animation below.Let's assume that the two balls are sliding on a frictionless,horizontal surface. Do not assume that this collision is elastic(though it might be). Here's what's given:
The direction of +x is to the right.The blue ball has twice themass of the red. Let's make them mb = 2 kg and mr = 1 kg.
The red ball is initially stationary.
The initial velocity of the blue ball, vbi, is 6 m/s, and itsfinal velocity, vbf, is 2 m/s.
1)Find the final velocity, vrf, of the red ball, in meters persecond. Enter only a single number (without units) beforesubmitting. If your answer isn't an integer, you've made a mistakesomewhere ! 2)The principle that I used to get the answer to theprevious question was conservation of ... 3)
the initial KE of the system (both balls) in this problem is:(give answer and show/explain how you got it) 4)
The final KE of the system (both balls) in this problem is:(give answer and show/explain how you got it) 5) was the collisionelastic?
